Hi Fabio,
Just have a question, the tcpci driver is not supported, so how do you manage to make SDP work?
I understand that the tcpci driver is required when a USB role switch is needed.
I am only using the usbotg1 as a peripheral.
Here are the logs:
On the host PC:
$ sudo uuu -brun spl flash.bin
On the console:

One issue that I observed and haven't had a chance to debug yet is that running 'ums 0 mmc 1' works only when issued for the first time.
If I interrupt with CRLC+C and then launch 'ums 0 mmc 1' again, it does not work.
This is unrelated to SDP and happens when I boot from SD card as well.
If you have any ideas, please let me know.
Thanks,
